Debugging action items :

  • Factor scrblnrd3 code into HiPerC layout for differential analysis
  • Read OpenCL spec to understand what, exactly, clCreateProgram and clCreateKernel are doing
  • Using gdb, set breakpoint just before clCreateKernel and print addresses and values of OpenCLData struct leading into segfault
  • Suspend all but one program with one kernel and test
